Twenty one soybean hybrids derived from a seven-parent half-diallel set along with their
parents were evaluated to estimate heterosis. Heterosis was significant positive for yield
in 16 hybrids over midparent and in 9 hybrids over better parent. Heterosis for yield was
generally accompanied by heterosis for yield components. For protein, five and for oil one
hybrid exhibited significant positive heterosis ovtr midparent. In view of the availability
of genetic male sterility, the study revealed good scope for commercial exploitation of
heterosis for yield and protein contents in soybean.
Keywords: Soybean, Glycine max, heterosis.
